But when it comes to the first flight of the plane, Yang Hui has experienced this kind of scene I don't know how many times, it stands to reason that there will not be much excitement in his heart, and not being surprised is the most basic quality. www.biquge.info But the actual situation is not the case, not only the on-site personnel of Hongdu are excited and worried, but even the entire AVIC Southwest, and even all the people who observe the work of the four first flights on the scene, which one is completely relieved, and which one is not excited?

"Hey! That one... Where is Yang Hui, the general manager of AVIC Southwest? Call him over first, I remember that he complained to me for a long time before, then I let him watch from the side on the first flight, and I couldn't let him run anymore, and last time he kept telling me that the progress of the fourth project was delayed, and the schedule node should be relaxed, but now it seems that these design and development teams under him do not cooperate with him! ”

The big leaders still remember that when they learned about the progress of the Secondary 4 project, Yang Hui said that he would delay the progress of the project at that time, and then the big leaders had already accepted this matter, but they didn't expect that this time there was suddenly news that the project progress had caught up, which was probably a small surprise.

Only then did he shake out all the previous things in front of a group of military leaders, and this time he must correct Yang Hui, just to see how deflated this guy looks.

And after Yang Hui was "corrected", he was also embarrassed in his heart, didn't this big leader want to tease himself! In the past few years, the project progress has been advanced, is it possible to make mistakes?

The feeling of being watched by a group of generals, Yang Hui said that we are really under pressure: "Leader! You really can't blame me for this, I got the project schedule of Hongdu before, which is indeed what I said at the time, but who knows that after I went back last time, I took out the funds you approved, which is terrible, that Hongdu was the first to issue a military order to grab back the node, and now I can have such a fast progress, all because of the funds in place! ”

It's hard to say anything else, but it's far-fetched, Yang Hui can still easily get involved, and attribute the acceleration of the progress of the Hongdu Secondary 4 project to the funds approved by the previous leaders, which not only explains the reason for the acceleration of the progress of the Secondary 4 project, but also indirectly explains Yang Hui's previous rules for fund allocation.

It must be admitted that Yang Hui's answer made the big leader very satisfied, and he shook his head in front of everyone: "Come on, you just want to say that you are open-minded from top to bottom in the southwest of AVIC, as long as you have money, you can say anything, right?" It's a pity, no matter how good you say, the state will not make any more investment, even if you count the projects in your company's hands now, there are a lot of them, which one can cost less? The state now has no extra funds, so you don't need to take eye medicine anymore. ”

was broken by a sentence in his heart, Yang Hui said that we can't help it, this Hongdu is such a virtue, and no one can do anything about him. Besides, Yang Hui doesn't think that any additional funds can accelerate the progress of Form 4 again, and sometimes after reaching the upper limit, it will inevitably be half the effort.

"Leader, what you said is wronged by our AVIC Southwest, just to say that this time Hongdu, now to have this progress is already the result of overtime, the chief designer of the aircraft has set up his home in the office, for this first flight, the relevant personnel closed training, we have not met with their families for more than a month, this time it is really desperate!"

Yang Hui has always opposed overtime overwork, but sometimes the opposition is also very pale, powerless, the entire AVIC Southwest company culture has been formed, that is, desperate can not fall behind the schedule, coupled with the entire republic's aviation industry from the beginning of this spirit throughout, Hong Du in the face of the project progress behind the situation, to work hard, Yang Hui is not good to say anything.

A group of people surrounded Yang Hui very helplessly, the first flight of the plane on the other side was on the bow, all preparations were completely ready, when the cockpit canopy was closed, the pilot's heartbeat must be unusual, after all, this was the first flight of the aircraft, after all, the bigwigs who watched the first flight had high hopes for this aircraft!

The old rule, first communicate with the tower side, get the take-off command, this is the steady push of the engine throttle valve, the light load state of the fourth began to glide forward briskly, the plane is definitely a good aircraft, adhering to the traditional concept of Hongdu design fighters, the take-off and landing distance must be short, the fourth is planned to be a fighter with short-distance take-off and landing capabilities.

Of course, at this time, the first aircraft was powered by the Russian-made AL-31F/N engine, and this engine did not have thrust vectoring capabilities, so according to common sense, the take-off and running distance of the current Secondary 4 was not as short as the design required.

These factors were considered by Hongdu when he designed the four prototypes, and even the commander-in-chief of the first flight on the scene also comprehensively considered the light load state of the first aircraft, and once again estimated the take-off distance of the fighter.

For example, this time, with the pilot pushing the throttle valve to the predetermined position, the plane was planned to slide smoothly in front of the viewing platform, and then take off smoothly. But not long after the time, the pilot in the cockpit already sensed that the plane was now a little disobedient to the command, and it seemed that the nose of the plane could no longer suppress the tendency to raise its head.

It's a bit embarrassing, the planned flight was supposed to glide gracefully and slowly past the viewing platform before taking off, but now that you sit down on this fighter, why is it suddenly so rebellious? Feeling the powerful force coming from under the wings of the fighter plane, and then looking at the viewing platform that is about to arrive in front of you, it is time to make a decision.

The pilots can already feel that the front wheels of the plane are beginning to float up as if they are floating up, and it is time to take off and make a decision, and they must not hesitate! Regardless of whether the guests on the viewing platform will be gods, the test pilot in the first flight has the absolute right to fly the aircraft, as long as the flight is safe.

In normal takeoff, after the fighter reaches the take-off speed, there will be a pulling up action, but this time it is different, the test pilot did not pull up, the fighter has already left the runway at a small angle, and at a height of five meters from the ground, the fighter passed smoothly in front of the viewing platform.

"Report, the minimum take-off speed budget of the fighter is wrong, and our plane entered the take-off phase ahead of schedule, over!"

It didn't take the pilot's report to report that the on-site commander had already discovered the situation, which really made people laugh and cry, the speed required for the plane to take off was actually slower than expected, what does it mean?

This is clearly that the design of the fourth middle school is too good, and the lift coefficient of the whole aircraft is much higher than the lift coefficient of the whole aircraft in the design, which proves that the aerodynamic design of the fighter is very successful, and it is beyond the predetermined requirements, which is a thrilling surprise.

"Received, we will analyze the specific reasons immediately, and now the first flight work continues, over!"
